Pampa City Hall. Construction of this and other major downtown buildings in Pampa came as a result of the Texas Panhandle Oil Boom of the late 1920s and early 1930s. Designed by architect William R. Kaufman to complement the Gray County Courthouse, which he also designed, the City Hall was completed in December 1930. The beaux arts style building features triumphal arch entrances with classical detailing and pilaster elements around the perimeter. Recorded Texas Historic Landmark - 1987 #3923
